PlumX: Nanoarchitectonics of bacterial cellulose with nickel-phosphorous alloy as a binder-free electrode for efficient hydrogen evolution reaction in neutral solution
Developing low-cost and efficient electrodes for hydrogen evolution reaction (HER) under neutral electrolytes remains an unattained milestone. We report a highly performing binder-free electrode through electroless deposition of Ni–P nanoparticles on bacterial cellulose (BC). Not needing carbonization to provide the electric conductivity, BC can maintain its excellent mechanical properties and thin fiber microstructure. The nanometric cellulose fibers facilitate the formation of small Ni–P nanoparticles, leading to more catalytic active sites.

#25N “International Day for the Elimination of Violence against Women”

On the occasion of the International Day for the Elimination of Violence against Women, the CSIC Women and Science Committee and the CSIC Delegate Committee for Equality have prepared the following joint communication. 

The ICMAB Gender Equality Committee at ICMAB works to ensure that there are no inequalities or discriminations for reasons of gender, race, age, nationality at ICMAB, is the main consultation point for anyone who has any issue regarding these topics, and makes available all the resources and tools (from CSIC, MCIN...) to the ICMAB staff and provides training in the matter, so they know what to do when something related to work or sexual harassment, inequalities, bias, or any other discrimination happens.

PlumX: Temperature-induced polymorphism of a benzothiophene derivative: reversibility and impact on the thin film morphology
The identification of polymorphs in organic semiconductors allows for establishing structure-property relationships and gaining understanding of microscopic charge transport physics. Thin films of 2,7-bis(octyloxy)[1]benzothieno[3,2-b]-benzothiophene (C8O–BTBT–OC8) exhibit a substrate-induced phase (SIP) that differs from the bulk structure, with important implications for the electrical performance in organic field effect transistors (OFETs).

PlumX: PS-b-P4VP block copolymer micelles as a soft template to grow openly porous nickel films for alkaline hydrogen evolution
Highly porous Ni films have been potentiostatically synthesised by micelle-assisted electrodeposition using custom-made PS-b-P4VP block copolymer micelles as a soft template. Two PS-b-P4VP block copolymers with PS/P4VP block ratios of 1:1 and 1:4 were used for the micelle-assisted electrodeposition, resulting in Ni films with large pores of diameters varying from 25 to 600 nm (1:1), and from 10 to 230 nm (1:4).

Recyclable optical bioplastics platform for solid state red light harvesting via triplet–triplet annihilation photon upconversion

PlumX: Recyclable optical bioplastics platform for solid state red light harvesting via triplet–triplet annihilation photon upconversion
Sustainable photonics applications of solid-state triplet–triplet annihilation photon upconversion (TTA-UC) are limited by a small UC spectral window, low UC efficiency in air, and non-recyclability of polymeric materials used. In a step to overcome these issues, we have developed new recyclable TTA-UC bioplastics by encapsulating TTA-UC chromophores liquid inside the semicrystalline gelatin films showing broad-spectrum upconversion (red/far-red to blue) with high UC efficiency in air.

PlumX: Charge-Transfer Complexes in Organic Field-Effect Transistors: Superior Suitability for Surface Doping
We demonstrate the key role of charge-transfer complexes in surface doping as a successful methodology for improving channel field-effect mobility and reducing the threshold voltage in organic field-effect transistors (OFETs), as well as raising the film conductivity. Demonstrated here for 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT) doped with 2,2′-(perfluoronaphthalene-2,6-diylidene)dimalononitrile (F6TCNNQ), channel doping by sequential deposition is consistently rationalized by the development of a cocrystalline structure that forms and evolves from the surface of the organic semiconductor film without trading the thin-film structure integrity.

PlumX: Continuous Carbon Channels Enable Full Na-Ion Accessibility for Superior Room-Temperature Na–S Batteries
Porous carbon has been widely used as an efficient host to encapsulate highly active molecular sulfur (S) in Li–S and Na–S batteries. However, for these sub-nanosized pores, it is a challenge to provide fully accessible sodium ions with unobstructed channels during cycling, particularly for high sulfur content. It is well recognized that solid interphase with full coverage over the designed architectures plays critical roles in promoting rapid charge transfer and stable conversion reactions in batteries, whereas constructing a high-ionic-conductivity solid interphase in the pores is very difficult.

PlumX: Ultrabright Föster Resonance Energy Transfer Nanovesicles: The Role of Dye Diffusion
The development of contrast agents based on fluorescent nanoparticles with high brightness and stability is a key factor to improve the resolution and signal-to-noise ratio of current fluorescence imaging techniques. However, the design of bright fluorescent nanoparticles remains challenging due to fluorescence self-quenching at high concentrations. Developing bright nanoparticles showing FRET emission adds several advantages to the system, including an amplified Stokes shift, the possibility of ratiometric measurements, and of verifying the nanoparticle stability.
